To @ZZ whom, it may concern:

Be it known that I, HENRI GALOPIN, a subject of the King of Great Britain, and a resident of Chancery Lane, Melbourne, in the State of Victoria, Commonwealth of Australia, have invented a certain new and useful Improved Mechanism for Automatically' Distributing Liquid Fuel, of which the following is a specification.

My invention while a plicable to any liquid relates more particu arly tothe distribution of liquid fuel for the purposes of lighting, heating, and the like. For simplicity I will refer to the liquid as kerosene, although my invention may be employed for other liquids for similar purposes.

Ihe object of my invention is to provide a simple automatic mechanism which will secure the delivery to the lamp, stove, or other point of consumption of aregulated supply of kerosene in such manner as to maintain the supply at a predetermined level and to prevent the supply rising above such level. Iaccomplish this by arrangingfor the kerosene to flow by gravitation through a nozzle approximately conical in formthe orifice of which also forms a valve-seat. The nozzle delivers the kerosene into a chamber which contains a float having a vertical spindle. As the chamber fills with kerosene such float rises, and with it the spindle rises. Such spindle contacts with a valve and in its ascent raises such valve and presses it against the valve-seat formed by the orifice of the supply-nozzle, thus shutting off the flow of kerosene. As the kerosene is drawn by consumption from the chamber referred to the float and spindle will descend, thus allowing the valve to fall and the fiow to resume. I arrange the service-pipe from such chamber and the casing of the chamber in such a manner as to permit of the height of the chamber being adjusted vertically to suit the required level of the point of consumption at the lamp, stove, or the like. I also provide an overflow arrangement which can be adjusted to suit the buoyancy of the float. I also provide a subsidiary chamber, float, and spindle to serve as an indicator of the state of supply of kerosene in the reservoir. I provide a reservoir for containing the main supply of kerosene, and I arrange at the inlet end of the principal service-pipe a handpump to start the flow and enable the kerosene to siphonout of the reservoir without requiring further attention.

In order to explain my invention more clearly, I will now refer to the drawings, which form part of this specification, where- Figure l represents in side elevation in a diagrammatic form the general arrangement of the mechanism. Fig. 2 is a vertical section of a portion of the mechanism. Fig. 3 is an enlarged view of the nozzle, valve, and portions of the surrounding casing.

The same letters of reference indicate the same parts in all the figures.

A is a wall-bracket fixed in any convenient position in the building and supporting a shelf B- Upon B is placed a reservoir C, containing the main supply of kerosene. I prefer to use for this purpose the tin or drum in which the kerosene is ordinarily purchased, perforating same for the reception of the siphon-pump D and also for an air-vent. The shelf B is'arranged to be of suitable size to permit of the tin of kerosene being lifted so as to embrace or immerse D as it rises, being then turned about a vertical axisand pushed onto the shelf. Y

E is the main service pipe, which may have one or more branches, as at E', the several branches, respectively, serving several valve mechanisms in different parts of the building. At the head or inlet end of E is fixed a pump D, comprising barrel a, plunger-rod b, plunger c, gland d, and handle e. The inlet end of service-pipe is bent atf and g to form a siphon.

When D has been immersed in the kerosene, the upward stroke of plunger c to its uppermost position will draw the kerosene up to the inlet h of E, and thereafter the whole contents of C will siphon out through E as fast as consumed.

Service-pipe E enters at K the small chamber F, within which is a fioat G, carrying a vertical spindle or rod H, passing upward within vertical pipe L, carrying at its upper extremity an index-plate M. Rod II carries a ppinter m, passing through a vertical slot 1n So long as sufiicient kerosene remains in C, and hence in F, to keep fioat G raised so long will pointer m indicate to Full upon the index-plate; but when the supply of kerosene is exhausted float G will fall to its lowermost position and carry with it H and fm, so as to indicate Empty The kerosene contained in F flows downward through orifice rnj of nozzle N into small IOO ITO

connecting-chamber O and thence into main chamber P, containing a float Q, carrying a vertical spindle or rod R, the upper endvof which when Q rises contacts with disk 1, attached to spindle s, attached to valve S, having a valve -face t, adapted to fit against edges of orifice n. The oil passes from chamber O to tank P, between the stem s and the walls of the guide-hole in which it slides.

As chamber P fills with kerosene Q rises, and with it R, till by contact between R and 7 valve S is pressed upward against n, thus shutting off the supply of kerosene. As soon as kerosene is drawn from P, Q falls slightly and S follows, thus permitting of a further inflow of kerosene into P.

V is the service-pipe leading to one or more lamps, or jets, or stoves, whose burners are all on the same level. V is arranged with a bend W, so as to be to a limited extent elastic or flexible, being rigidly held to a wall or to the frame of lamp or stove, as atX. Thus while X remains a rigid connection the whole of the mechanism comprising chambers P and F and their attached parts are capable of vertical adjustment. For this purpose P carries rigidly fixed to it on its exterior a preferably T-shaped slotted bracket Y with slot w, engaging with thumb-screw Z, which latter is screwed into the wall or to the frame of lamp or stove and acts when tightened up as a clamp to hold the mechanism rigid. Thus Z being loosened the whole mechanism is capable of accurate vertical adjustment of height, whereupon Z is again clamped. The object of this vertical adjustment is to insure that the valve S will come into action when the level ofthe kerosene in the lamp or stove has risen to a predetermined level in same, thus preventing an excessive supply of kerosene to same.

T is a T-shaped pipe attached to and emerging from chambers P, its vertical leg having at its lower extremity a plug or cork g, held in place by cap y. Through y and g there passes upward a pipe p, which is capable of.

adjustment within T as to the level of its upper orifice. p is an overflow-pipe and leads to any convenient point of discharge. I provide these arrangements for the adjustment of p in order that the overflow-.level may be properly predetermined by the manufacturer, having regard to the buoyancy of float Q, which will of course vary slightly in different mechanisms.

It will be found that the supply of kerosene required for a lamp or stove is somewhat greater whenthe Haine is first lighted than when, after burning for a short time, the

burnerbecomes heated. For this reason I provide for having the buoyancy of fl oat Q adjustable. I accomplish this preferably by placing within the chamber a weighted lever having weight a', lever-arm b, and pivot e', connected to side of chamber, Such lever-arm yof same.

has pivoted to it a rod c', passing upward through top of chamber P and embraced by a thumb screw d. The turning of such thumb-screw operates to draw the rod c, and hence b, upward, thus lifting the weight a off the float, thereby increasing the buoyancy By these means the weight a is allowed to rest upon float Q when the lamp or ,stove is first lighted, being shortly afterward raised off the float by the rotation of d.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isW
